+    <td valign=\"top\">Changed the models to use by default an <i>&epsilon;-NTU</i>
+                       approach for the heat transfer between the fluid and the slab
+                       rather than a finite difference scheme along the
+                       flow path.
+                       Optionally, the finite difference scheme can also be used
+                       as this is needed for some control design applications.<br/>
+                       The new <i>&epsilon;-NTU</i> formulation has shown to lead to 
+                       about five times faster
+                       computation on several test cases including the models in
